Just found this thread while looking for a 3rd party TMS solution for the Leaf. But has anyone posted anything about such a solution?

If there isn't one, what would be involved in doing a DIY one? I don't believe there's an air-gap between the pack and the chassis, but there is a gap between the pack and the underbody cover. I'm thinking of attaching a flat nozzle to a blower that's powered off the 12V battery? Anyone familiar with the underside of a leaf?
